Hay people. My engine warning light has come on with the code suggesting misfires. I've taken it my local VW specialist and they replaced the spark plugs and tested the coil pack with one they had spare. He has now told me it is the injectors on 1 & 2 that need replacing. The garage has quoted me £1,000 to do this.
Is this reasonable as to me it seems expensive! Also are the programmed units or can I simply fit them myself. I know the job requires manifold off etc which I'm more than happy to do, just seems excessively priced.
Let me know guys as can't leave it missing ATM but begrudge paying out a stupid amount for a simple swap I can do myself.
Fuel injector replacement. Should I just do myself?

Re: Fuel injector replacement. Should I just do myself?
If you have the experience and more importantly the tools - do it yourself.
I wouldn't go about doing this without the workshop guides (or at least a user guide on the net) - you need to know torque specs, and also be aware of any nice little surprises before hand.
I've done it on my 1.4 tsi twincharger, 5 hour job - much harder than the 2.0 tsi as its a more complex engine with the manifold at the back.
Job wouldn't have been possible without some tools that ya wouldn't normally have (crows feet, short stub spline bit etc)
Also be cautious of removing the fuel rail - they tend to pull injectors out and you will need to renew the Teflon seals if they do come out...which requires a special toolkit (no other way to replace the Teflon seal without the kit). If it was me I would pull the other 2 anyway and clean them along with renewing all the seals.
The injectors are not programmed units - you can just replace them with like for like. The ecu will relearn any necessary flow adjustments.
Half the cost of the £1000 would have been the injector cost - they are £200+ each from VW.
